    Some users may find that ffvp9 is a lot slower than advertised on 32bit x86; this is correct, most of our x86 SIMD only works on 64bit x86 machines. If you have 32bit x86 software, port it to 64bit x86. Canít port it? Ditch it. Nobody owns 32bit x86 hardware anymore these days.
    Fixed that for him.
    There's lots of 32 bit ARM devices out there, as well as a few other architectures.

    ARM rarely has computing power for software codecs so it uses DSP addon circuits.

    the most important thing is the quality, if the quality suck like vp8, this codec won't be interesting for me.

    Video quality with vp9 is definitely better than vp8, in many cases it beats even h.264 (as encoded by x264), but it's not quite as good as h.265/HEVC. However, while it may not be better than HEVC, it's still the best free video codec currently available. At least until Daala comes and takes the title, hopefully, but that might take a while.

    If all we care about is quality, surely Daala would take the reigns there... (whenever it's released :/)

    It's hard to say that Daala has the best quality. In fact, at this moment, it has no quality whatsoever.

    As a game developer, I wouldn't be surprised if VP9 ends up being heavily used in video games. Vorbis is already heavily used in games, since it's easy to integrate and developers don't have to pay a licensing fee to use it.

    At the moment, Bink video is probably the most widely used video codec in games, even though it has rather terrible compression. Bink isn't free, but it's royalty-free, which is way more important for game developers.

    The excellent audio quality doesn't hurt either. Vorbis gives even the best proprietary audio codecs a run for their money and now equally free Opus beats them hands down.

    The choice isn't as simple in video codecs, but vp9 is certainly not a bad pick as soon as it's practical from an implementation standpoint.

    Indeed and future 64-bit ARM devices already have VP9 taken care of since hardware decoding is built into the next gen of GPUs while current 32-bit ARM devices can use the commercial software VP9 decoders which use the GPU's floating point hardware for decoding.
